    Volume between two surfaces???

    hi guys,

    i hope you can help with this, how to find the volume between those surfases:

    [tex]x^2+y^2+z^2=0[/tex]
    [tex]z=\sqrt{x^2+y^2}[/tex]

    thanks in advance

    What have you done so far? By the way, I think that first equation is wrong.

    If the first equation is correct, then the answer is very simple:
    Since the set of all (x,y,z) satisfying x2+ y2+ z2= 0 is the single point (0,0,0), the volume of the set is 0!
